Data acquisition systems are devices that measure voltage, temperature, pressure and other physical quantities. They convert signals from one form to another, often analog signals to digital signals. Analog to Digital Converters (ADC) are important components in these systems, responsible for converting analog signals to digital signals. The ADC10DV200CISQ/NOPB is one such ADC, with a range of usage and unique working principle.

Application Field of the ADC10DV200CISQ/NOPB

The ADC10DV200CISQ/NOPB is an eye diagram-accurate test and measurement device with built-in test functionality and emphasis on repeatable and malicious testing. This ADC has many applications in the communications, broadcasting and sensing markets, including high-fidelity audio, automotive infotainment and speech recognition. As its own custom-designed power rail circuit helps to ensure auto-scaling and break/make detection, it can be used in various tests and measurements, including full-channel testing of customer devices, stress testing and fault detection.

The ADC10DV200CISQ/NOPB also allows efficient design of portable devices since its internal clock oscillator supports up to 10MHz operation. It also brings intelligence to loads and sensors, with differential input stage and other features that ensure precise measurement and improve accuracy. This ADC is designed to survive extreme environmental conditions, having a pulse width modulation temperature range from -40°C to +150°C.

Working Principle of the ADC10DV200CISQ/NOPB

The ADC10DV200CISQ/NOPB works with its unique architecture, the Supercharged Vintage Voltage Digital-to-Analog Converter (SVVDAC). This architecture combines several unique features, including a switched-capacitor filter, variable length flash and sequential conversion techniques, to achieve high-performance conversion.

The Test and Measurement mode in the ADC10DV200CISQ/NOPB starts with a banded (dual-tone) ADC that allows switching between two different banded signals without affecting the input frequency. Each banded signal is then converted to a digital signal using a pulse-width modulation technique, along with a digital clock that synchronizes the operation. The digital signal is then filtered with a switched-capacitor filter, which removes noise and improves signal accuracy. The filtered digital signal is then sent to the sequential conversion stage to be further processed.

The sequential conversion stage of the ADC10DV200CISQ/NOPB consists of two comparators and a comparator-controlled switch. The two comparators compare two analog inputs (an input and a reference) and determine the output value of the switch, depending on the relationship between the two inputs. The output of the switch is then sent to the DAC register, where the bits from the signal are stored. This signal is then passed to the VDDAC, where the signal is converted to an output voltage. The output voltage is then measured for testing and measurement.

Conclusion

The ADC10DV200CISQ/NOPB is an eye diagram-accurate test and measurement device with a wide range of applications. Its Supercharged Vintage Voltage Digital-to-Analog Converter (SVVDAC) architecture combines various features, including a switched-capacitor filter and sequential conversion techniques, to ensure high-performance conversion. Its power rail circuit helps to ensure auto-scaling and break/make detection, and it is designed to survive extreme environmental conditions. The ADC10DV200CISQ/NOPB is therefore a great choice for many digital signal processing applications.
